MOTOR AND FRAME THEREFOR FOR MOTOR-VEHICLES.

SPECIFICATION forming part of Letters Patent No. 7'76,023, dated November 29, 1904. Application filed March 21, 1904. Serial No. 199,245. (No model.)

To all whom it may concern.-

, Be it known that I, NORMAN T. HARRINGTON, a citizen of the United States, residing at Detroit, in the county of 'Wayne and State of Michigan, have invented certain new and useful Improvements in Motors and Frames Therefor for Motor-Vehicles, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to motor-vehicles, and has more particular referenceto the construction of the frame and motor therefor, as hereinafter set forth. a

In the drawings, Figure 1 is a plan view of theframe and motor. Fig. 2 is a side eievation thereof. Fig. 3 is a perspective view of the enginecasing. Fig. i is a perspective view of the detachable bearing cover-plate. Fig. 5 is a section through the bearings, show ing the engine-casing in elevation. Fig. 6 is a plan of the crank-case.

A is the frame, which is of substantially rectangular form, comprising the longitudinal side bars a and the cross-bars 6.

B is the motor-casing. This is arranged longitudinally of the frame A intermediate the bar a and is formed of a crank-casing which extends between the bars t, to which it is firmly attached by bolts or other securing devices. Thus the crank casing forms a strengthening brace or strut between the bars 5, which increases the rigidity of the structure.

The crank-casing B is preferably formed of a single casting having at one end the lugs c for attachment to one of the bars 7) and at its opposite end the projecting lug (Z for attachment to the opposite bar 7/. The intermediate portion is in the form of a hollow casing which is open at its upper end, said opening being adapted to be closed by a cap O, bolted or otherwise secured thereto. The opposite side walls a of the casing are slotted at f for the admission of the boxes or bearings that support the crankshaft, and these slots are in a plane inclined to the axis of the casing, for fihe purpose that will be hereinafter set fort The lower half-box for the crank-shaft bearing is preferably formed by the projecting flange on the casing, which is babbitted. or otherwise hushed for forming a direct bearing for the shaft. The upper half of the bearing is formed by the detachable block D. This is provided upon its opposite sides with guide-flanges y, which embrace projecting flanges/i on the casing adjacent to the siotf. The bearing portion 2 of this block is formed in the lower end thereof, being babbitted or bushed to correspond with the complementary bearing in the casing.

E is a key for setting up the bearing-block D, which passes through the registering apertures in the flanges h and a 'keyway in the block I). The outer end of this key is preferably provided with a threaded shank j, which passes through the apertured lug Z; and is secured in different positions of adjustment by clamping-nuts Z on opposite sides of said lug.

F is a-clamping-bolt which passes through the flanges it and a registering slot in the box I) and serves to firmly clamp the flanges against the block to hold the latter in position and to also render the entire casing rigid.

With the construction just described the crank-shaft may be placed in position by first entering it through the slots f until it rests in the lower bearings at the bottom of said slots. The blocks 1) are then inserted in the slots and the keys E adjusted to set the bearing against the shaft, after which the clamping-bolts F are tightened to render the structure rigid. The cap C may then be placed in position and will complete the closure of the casing, so as to make a practically oil-tight and dust-proof housing.

As has been stated, the casing B forms a rigid bracing-strut between the cross-bar b and serves to increase the rigidity of the frame A. This casing also forms the sole support for the cylinder G, which isbolted or otherwise clamped to the end of the casing B in axial alinement therewith and projects forward of the cross-bar 7) free from other-attachment. Thus whenever it is desired to dismount the ward direction.

engine by removing the block D and detaching the crank-shaft all the working parts can be removed from the casing B, which latter may be allowed to remain permanently in position in the frame. The engine is preferably arranged with the cylinder G extending forward, while the drive connection to the rear axle extends in a downward and rear- This arrangement permits of arranging the entering-slotf for the crankshaft so that the bearings at the lower ends of said slots will be arranged to receive the stress due to the load on the drive-chain. Furthermore, by constructing the engine so that the crank turns under in the forward stroke of the piston the stress on the crank during the forward travel of the piston will also be directly upon the bearings at the lower end of the slot f. Thus the detachable bearing-block D is subjected to but slight stress.

The frame A forms the support for the vehicle-body, (not shown,) and it is supported on the axles H and 1, preferably by forwardly and rearwardly inclined spring-arms J. These spring-arms are secured to the under side of the longitudinal bars a of the frame, which are preferably formed of angle-bars and at their free ends are secured to the axles.

In order that the drive-chain K, which connects the sprocket L on the crank-shaft with the sprocket M on the drive-axle, may be maintained at uniform tension during the flexing of the spring-arms J under load, the crankshaft N is located approximately at the center of movement of said arms. This arrangement is possible by reason of the fact that the engine is arranged with its cylinder extending forward. This brings the vertical plane of the crank-shaft in line with the point of bending of the spring-arms. Furthermore, the casing is arranged with its axial plane substantially in the horizontal plane of the lower leaf of the springs, and thus the axis of the shaft will substantially coincide with the center of turning of the spring-arms.

The valves and the igniter for the engine are preferably operated by the longitudinally- J extending shaft 0, which is driven from the crank-shaft through the medium of wormgears. For housing this mechanism I preferably form integral with the casing B the projecting casing P, which also forms the bearings Q for the shaft 0. A complementary portion R of this casing is formed integral with the block D and, together with the l detachable plate S for the casing P, the mechanism will be completely housed. The crankshaft N extends across the frame A and is preferably journaled in the bearing T and at its outer end secured to the longitudinal bar a of i the frame. In the space between this bearing and the crank-casing is arranged the flywheel U and the transmission-gearing V. To permit of removing the crank-shaft from the l casing B through the slot f, clearance must l be provided for the fly-wheel, and to this end the forward cross-bar 7) of the frame is preferably bent downward, both to form a support below the casing and also to give clearance for the fly-wheel during the attachment of the shaft.

lVhat I claim as my invention is- 1. The combination with a crank-shaft of a casing therefor, having an opening therein for the passage of the crank and entering-slots in its opposite walls for the reception of the crank-shaft, filling-blocks for closing said entering-slots and a cap for closing said opening.
